The plastic shell is made of polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinylidene fluoride (PVDF) and other tower packing. It has the characteristics of high void fraction, low pressure drop, low mass transfer unit height, high flooding point, full gas-liquid contact, small specific gravity, and high heat and mass transfer efficiency. These plastic bulk fillers operate at temperatures ranging from 60 to 280 degrees Celsius. Widely used in petroleum, chemical, chlor-alkali, gas, environmental protection and other industries of the packed tower.
● the perforated structure and some vertical vertical axis inhibit the solid flow through the packed bed is more likely to be liquid scour caused by pollution. Free flow of gas.
● higher liquid handling capacity, high gas capacity and low pressure drop, lower aspect ratio increases operating capacity and reduces pressure drop, low pressure drop high efficiency improves separation effect and reduces height of newly installed tower.

perfo rmance | 1. The open-hole structure and some vertical and vertical axes inhibit the pollution caused by liquid washing more easily on the solid flowing through the packed bed, enabling the free flow of gas | ||
| 2. The pressure drop is smaller than that of the pall ring and the rectangular saddle ring | |||
advan tages | Open pore structure and some vertical longitudinal axis inhibited the flow through packed bed of solids is more likely to be fluid scouring caused pollution. Higher liquid handling capacity, high gas volume and low pressure drop, the low aspect ratio increased operating ability reduced the pressure drop, low pressure drop to improve the separation effect with high efficiency, reduce the height of the installed in a new tower. | ||
| Strong corrosion resistance, large void, energy saving and environmental protection, low cost, light specific gravity easy loading and unloading. | |||
| field | Plastic bulk packing with a temperature of 280 degrees Celsius, widely used in petroleum, chemical, chlor-alkali, gas, environmental protection and other industries in the packed tower. | ||
